From the problem, we have :


x^2+10x+n

To make it a perfect square trinomial, we will use the formula :


n=((b)/(2a))^2

and we can factor the trinomial as :


(x+(b)/(2a))^2^{}

a = 1 and b = 10

so n will be :


((b)/(2a))^2=((10)/(2*1))^2=5^2=25

The value of n is n = 25

and the factor of the trinomial will be (x + 5)^2
